Well, I have been been buying some goodies the last couple of days. I am getting the carb mentioned above, and also ordered a carter fuel pump. I was thinking that the pump was 7psi, but after I ordered I realized it was 8. Will this be to high? If so I have a regulator, but will it hurt a mechanical pump to regulate it down? The only carb I really have experience w/ is my cc quadrajet so I dont really know. I put a t56 in and so I really wanted a dp carb. What should I do w/ the fp. Do I need to order a different pump or can I make this work? I have run a best of 9.410 in the 1/8 mile, but it feels like I am running out of fuel up high w/ my current pump(still using quad by the way). I also have a set of sportsman II's that I have started porting and will finnish soon if I could get enough free time.

Thanks

Ben

 

Use the regulator ..set it to 6psi and run it.My Demon 750dp loves anywhere from 5.5-6.5psi.

 

I'm running just the stock pump putting out 6 psi, no problems

 

What is the setup you are running? I have been running a quadrajet w/ stock pump, and it seems like it is running out of fuel up high. I guess it could be the carb, but I am putting a new pump on when I do the carb anyway just to eliminate that as a possibility.

Speed Demon 750 stock replacement fuel pump for this engine. I'm gonna get one of those Carter pumps and a Mallory 3 port, that'll all be used when I switch to a 350. You might want to check your fuel filter and float level if it feels like you're running out of fuel.

 

Well, the carb I am running out of fuel on is the stock quadrajet, so I am not going to mess w/ it since I am putting the demon on.
